The metric you're looking for is QALY "quality adjusted life year". It's studied a lot in health economics but generally disregarded wrt covid because we don't have 2060's actuarial tables yet.
Yes there is evidence that 10-30% of covid infections have not resolved at 6 months
which is roughly what SARS 1 looks like (and those people are still sick). But we still can't definitely say that 35 year olds who catch covid will lose 10 years off the end of their life so it's disregarded in our decision making.

That isn’t relevant to the 10 year statistic although it is an interesting point - you are saying the final result for years of life lost due to Covid could be a higher number than 10 years (after we get to finally tally the numbers in the decades to come as people die). Depends on how you paint your statistics I guess. [para edited to add clarity]
